Pros: Card and Driver install was easy

USB3 speeds worked as advertised with my seagate USB3 backup HDD.

Cons: 1. This card is taller than I expected. I found that it bumps up against the oversized CPU cooler in my slot. So far it works and only time will tell if the heat from the cooler will affect this card.
2. You have to plug in the molex power. I had to connect an extra set to my power supply which added some cable clutter, but I knew to expect this.

Other Thoughts: I read about the backwards compatibility between USB3 and USB2 but didn't realize that although the technology is backwards compatible, the USB3 wiring is different. This means that you need USB3 cables to get the benefits of USB3. Also, if your case has the old USB2 connections on the front, those won't work with the USB3 header on this card. I thought I would be able to plug the USB from my case into the header on this expansion card but that didn't work. For now, I have 2 USB2 in front through my motherboard and 2 USB3.0 on the back of the computer through this expansion card.

HOOTOO makes another expansion card with 4 USB3.0 connectors in back. If I had realized the difference in the header connection I would have ordered that expansion card instead.

Oh well, not the card's fault, just a learning experience.

Pros: This drive was easy to setup. I plugged it into my router and my networked computers all detected it.
The price is decent for 2TB of storage.
I didn't experience the firmware issues like others have.

Cons: I run a wireless network and won't be taking advantage of the theoretical 1Gb connection. My laptop and desktop are connected to my router at around 100Mb. Trying to transfer files is just painful.

I get between 500KB and 3MB per second when trying to copy files to this NAS. I spent a few days testing out other options but my network is not up to the task. I would probably need to upgrade my network just to get passable performance so I am returning this drive. This may not be the drive's fault but I am not going to spend the extra time troubleshooting my network just to backup my two computers.

Other Thoughts: I liked the idea of a NAS but after giving it a shot, I decided it is just not practical for my needs. I replaced this NAS with a 3TB USB3.0 external backup from Seagate. I now get around 37MB / sec and haven't looked back.
